CIGAR-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 752,733, dated February 23, 1904. Application filed October 20, 1902. Serial No. 128,013. (No model.)

To all whom, it may concern:

Be it known that I, OTTO WARTMANN, a subject of the King of Great Britain, residing at 681 High road, Tottenham, in the county of Middlesex, England, have invented new and useful Improvements in Cigar-Making Machines, of which the following is a specification. I

This invention relates to improvements in the mechanism of cigar-making machines having flexible rollers working on rigid curved rods, substantially as described in the specification of the United States patent granted to me and dated May 24, 1898, No. 604,445.

This invention has for its object the simplification and improvement of the machine and parts thereof both in respect to its frame and mechanism and the consequent rendering of it more convenient and easy to use and so that a greater speed of turn-out may be obtained and maintained. The flexible rollers and the bent rods carrying them are essentially the same as described in my said patent except in some details; but the method of making these rollers, the manner in which these are mounted, the frame carrying and supporting them, and the arrangements for rotating the rollers are all more or less considerably changed and improved in this inven tion.

My present invention comprises two essential partsfirst, the nest of four flexible rollers between which the cigar is made and the mechanism forming part of the same, and, secondly, the mounting and mechanism for driving and otherwise, comprising a base-plate on suitable supports, on which plate are journals carrying the spindles of two horizontal and parallel driving-cylinders, placed adjustably at such distance apart as to conveniently admit of the nest of flexible rubber rollers being inserted between them, and on the opposite ends of such spindles are the pulleys and ratchet arrangement by which the apparatus is driven. The four cigar-shaped flexible rollers are carried on bent rigid axles, here inafter referred to as rods, and I mount the said rods in pairs, each pair of rods being so mounted that the members of it are The plates to which the other ends of the rods are fixed are made with their internal edges sharp at the part .9, where the pointed end of the cigar comes, so as to cut olf or facilitate the cutting off of any excess of leaf or filling which may project beyond the end of the cigar. The driving mechanism, including the ratchet and pulleys and other parts related thereto, is made reversible, so that the machine may when being put together be mounted either to Work to the right hand or to the left, and thus the necessity of having two sets of stampings is avoided.

In the accompanying drawings, Figure 1 is a side elevation of one of my machines; Fig. 2 is a plan of the same. Fig. 3 is a section on the line 1 1 in Fig. 2 looking in the direction of the arrow 2. Fig. 4 is a section on the line 3 3,'Fig. 2, looking in the direction of the arrow 4. Fig.5 is a plan of the framework carrying the flexible rollers, comprising the bent rods and the fittings on which they are mounted. Fig. 6 is a detail drawing showing the mechanism for raising and lowering that is to say, opening and closingthe nest of rollers. Fig. 7 is a plan view of the under side of the machine. Fig. 8 is a section on the line 5 5 in Fig. 7' looking in the direction of the arrow 6. Fig. 9 is a plan of the under side of the carriage removed from its slides. Fig. 10 is a detail drawing showing an end view of the blocks into which the ends of the rods carrying the flexible rollers are inserted and the joint thereof. Fig. 11 is an end view showing details of the fittings of the opposite end of the flexible rollers, together with the driving-cylinders.

Fig. 15 is a cross- Figs. 12 and 12 show desection on the line 7 7 Figs. 16 and 17 indicate the genesis of the curves proper for the rods 6 b I) 6.

Referring to the letters of reference, a a a a are four cigar-shaped flexible rollers between which the cigar is made.

I) b b b are rigid bent axles upon which the flexible rollers work and which are hereinafter referred to as rods.

0 0 are two parallel horizontal driving-cylinders placed adjustably at such distance apart as to conveniently admit of the flexible rollers being inserted between them. The said cylinders are carried on spindles cZ cl.

e is a base-plate on supports 6', adapted for securing the apparatus to a table.

ff are journals cast onto or forming part of the base-plate e, and f f are journals carried on the adjustable plate g. The plate g slides on bearingson the plate 6 and is drawn forth or back by the adjusting-screw h, with an attached collar it working against bearings 7L2, forming part of or fixed to the plate g. Another screw, 71, serves to clamp the plates 6 and g together when they have been duly adjusted. Pulleys j j, keyed on the shafts d, are caused to move synchronously by a rubber band or other belt passing round the two. The pulley in runs idle on the spindle d and carries a pawl m,having the usual actuating-springm";

This pawl m is arranged to engage with a ratchet-wheel Z, fixed upon the spindle (Z, and is so arranged that upon a rotary motion being given to the pulley in one direction motion will likewise be given to the pulley 1', while, on the other hand, motion being given to the pulley k in the opposite direction the pulley j will remain idle. The pulley 76 is driven alternately backward and forward by a cord connected with a treadle operated by the users foot.

The flexible rollers are made in the exact shape of the cigar to be produced, (except that they are a trifle longer on account of being bent,) and the diameter of the roller is at any and everyrpoint the same as that of the cigar at the corresponding point.

The shape to be given to the bent rods is determined by the. shape of the cigar to be made, and different sets of flexible rollers are required for every different sizefor shape of cigar.

If a cigar w of the pattern it is desired to produce is laid on a flat surface w as shown in full lines in Fig. 16, and if its ends are bent down so that the two ends touch the said surface and the cigar lies evenly on the surface between them, as shown in dotted lines in Fig. 16, the line 00 m 00 will represent the curve required to be given to each of the bent rods Z) Z) 6 Z) in order to produce similar cigars, except that some -part of the distance between its ends having been taken up by reason of the curved figure given to it the length must be restored by a small addition intercalated in the middle part of it. Fig. 17 represents the same line :22 00 m but with an intercalary addition :20 of such size that the distance between 01/ and 00 in a direct line is equal to the original length of the cigar. The flexible rollers a a a a are before they are placed on the rods 6 symmetrical and are with their ferrules of the form and dimensions of the cigar except as to length, which is greater than that of the cigar by a distance equal to Q2 When one of these is placed on one of the rods 1), it will be bent into the figure shown in dotted lines y y in Fig. 17 leaving a space between its inner surface and the line w w equal to half the diameter of the cigar, and therefore between it and the opposite roller a space equal to the diameter ofthe cigar. seen that if these conditions are fulfilled a cross-section of the rollers with a cigar be tween them is as represented in Fig. 15-that is to say, the rollers are of the same diameter as the cigar, and, further, it is convenient that the lines connecting the centers of the rollers and crossing in the axis of the apparatus should make with each other I an angle of about seventy-two degrees andone hundred and eight degrees, respectively.

For the sake of greater firmness and stiffness in a part of the apparatus which would otherwise be weak I make the two members of each pair of rods I) 6 out of one piece of metal that is to say, I take a piece of wire double the length of one rod and fold it over in the middle, making a sharp bend, and hammering the two limbs close or nearly close up to each other. I then' upset the folded end, so as to produce a flat end and so as to form a small flange or flattened extension of the end at right angles to the length of the wire, and thus obtain a running-surface against which the endof the ferrule 19 works. Through this upset portion or flange and partly between the wires I drill a hole through which a rivet p is passed and through the plate 17. and the whole further secured by brazing the joint. The rods must be given the shape required with aconsiderable degree of accuracy.

I fit the ends of the rollers with brass or other metal ferrules 0 0 and p p, the latter being made of the exact conoidal form which is to be given to the end of the cigar.

Coiled springs q q, compressed between the blocks 1* 9" and the ends of the rollers a, hold the latter against the running-surface at the opposite end of each of the rods Z), which are fixed, as hereinbefore described, to the plates 01, which are pivoted to plate 8.

The blocks 1' 1" are pierced for the reception of the ends of the rods 6, which rods are each secured in position by the split pin 20.

The four flexible rollers 60 to, together with the rods 6 and the fittings immediately connected therewith, are herein referred to as the It will be nest of rollers, and the said nest of rollers is separable from the driving mechanism, from which it may be detached by the removal of a clamping-screw n and by reason of the bent rods carrying the flexible rollers being fixed at one end into the jointed block 1' rand pivotally fixed at the other end by the plates at to the plate 8. The nest of rollers is integral in itself and separable from the other parts.

The blocks r r. are jointed together at r that is to say, about seven millimeters, a little more or less, below the central or axial line of the cigar being made and to the block 1* is attached a slotted arm 9*, which is adjustably attachable to the journal t, which works freely on the spindle OZ. A set-screw 0), passing through'the slot in the arm r attaches it adjustably to the journal t. A tailpiece t on the journal t is jointed to a link 29, with a crossbar 6 The link t is slotted at t" and Works on fixed pin t By manipulating the crossbar 6 and the said link the operator can raise or lower and so open and close the nest'of flexible rollers at pleasure, the roller performing a rolling motion round the driving-cylinders, the surfaces roll on each other, the two upper rollers becoming separated and the two lower rollers being brought nearer together. The slot of the link which works over the pin i has angle extensions, forming stops in such wise that it will not allow the rollers to move from either the raised or loweredthat is to say, the opened or closedposition without the slotted link being operated.

The method of using the machine is as follows: The operator opens the rollers a by the cross-bar t and places a quantity of fillingtobacco between the rollers, the space between which when the rollers areso opened forming to all intents a measure and holder of the quantity of filling required. The operator closes the rollers, which she then rotates by several strokes of her foot on the pedal. The edge of a binding-leaf is then inserted between the rollers, and being held and guided by the operator as it is drawn in binds the filling. thus forming the bunch of the cigar. A, covering-leaf is next fed spirally round the bunch and makes a finished cigar. The rotation being perfectly under the operators control, the leaf is guided and wraps the pointed end without difliculty, and a touch of cement conveyed by the operators fingers prevents the leaf afterward unrolling. The motion of the upper near roller is such that it smoothes out any Wrinkles in the leaf and greatly contributes to the ease with which it is evenly and smoothly wound. In order to change the set of flexible rollers with their mounting for anothersay larger or smallerset it is only necessary to remove the clamping-screw o and lift the one set out, then having adjusted the distance from each other of the driving-rollers, to put the other set in place, when the revolution of the driving-cylinders will cause the nest to find its 'central position, and the clamping-screw be ing replaced all is ready for work.

In the foregoing description of the machine it has been necessary to recapitulate some of the features described in the specification of my Patent No. 604,445, and it will be understood that I do not desire to claim as part of my present invention anything described or claimed in the specification of my said Patent No. 604,445; but
